For each upload, a new document with the file attached is created.

Install this package with pip:

pip install -U django-couchdb-storage

Add it to your INSTALLED_APPS in django settings:

INSTALLED_APPS = [
    ...

    'couch',
]

And and configuration to point django to your couchdb:

DEFAULT_FILE_STORAGE = 'couchdb_storage.CouchDBStorage'
COUCHDB_HOST = 'http://127.0.0.1:5984'
COUCHDB_DATABASE = 'django_storage'
COUCHDB_USER = ''
COUCHDB_PASSWORD = ''

Right now, this package assumes that content from the storage database can be read anonymously. Writes are authenticated. It is also assumed, that the db host can be accessed publicly.
